I want to load source code from a url, process its content and then load the url (with the processed info) to the user. How can that be done? (Is it possible using Javascript?)
Thank you in advance!
You need ajax. Using jQuery:
$.ajax({
type: "GET",
url: "your url",
success: function(data) {
alert("OK");
},
error: function(error) {
alert("error");
})

I'm getting XML data via jQuery, but the XML I am using has 5,000+ pieces of data I want to get. When my page tries to get the data after a few seconds my page freezes and shows "This page is being slowed down" and then crashes.
Is there a way I can get the data without the page crashing? Maybe slow the process down so it doesn't handle so many processes at once? Here is the code I'm using to get the XML data:
$(document).ready(function() {
$.ajax({
type: "GET",
url: "mymxl.xml",
dataType: "xml",
success: function(xml) {
$(xml).find("programme").each(function() {
$("xmlcontent").append($(this).find("title").text());
});
},
error: function() {
alert("An error occurred while processing XML file.");
}
});
});
I am trying to reload only part of a html page using jquery after a ajax call and everything I've tried gets me 404 not found. Does the jquery.load not work with node js and if so what is a workaround to get one div to reload without reloading the whole page?
$.ajax({
url: "http://localhost:3000/high",
type: "GET",
datatype: "jsonp",
success: function(data){
console.log(data);
var highbtn = JSON.parse(data);
console.log(highbtn);
$('#high').load('/Public/userphotoview.ejs' + ' #high');
},
error: function(){
console.log("error fetching data");
}
I'm trying to get currencies rate from the URL:
CURRENCY
It works perfect from browser and also from Android java using REST API.
Now I'm trying to get it from JS using JQUERY AJAX.
I use this code:
function handleJson(data)
{
console.log(data);
}
$.ajax({
url: 'http://www.boi.org.il/currency.xml?curr=01?jsoncallback=handleJson',
contentType: 'text/xml',
success: function(result) {
alert("XML File is loaded!");
alert(result);
},
async: true,
dataType:"jsonp",
type:"get"
});
I see in the log that content arrives but I can't handle it.
Here the screenshot
I need to detect client side if a requested file (with XMLHttpRequest) had a 301 response. The reason of doing this is because I need to request other files related to the file where user has been redirected and not related to the first one requested.
Any way to detect this response status code using JavaScript or JQuery?
Thanks.
jQuery ajax callback function gives out a lot of info
$.ajax({
url: "test.php",
type: "GET",
data: {},
dataType:"json",
success: function(resp, textStatus, xhr) {
//status of request
console.log(xhr.status);
},
complete: function(xhr, textStatus) {
console.log(xhr.status);
}
});
You can use $.ajax with jquery
It has everything you need here : http://api.jquery.com/jQuery.ajax/
If you look at "statusCode" explaination, you will see you can make something for every code
Can anyone point out why my JavaScript function is falling into the error function rather than the success function? Firefox on Ubuntu
$(document).ready(function() {
console.log( "Start" );
$.ajax({ type: "GET", dataType: "html", url: "http://slashdot.org",
error: function(request, status) {
console.log("Error");
},
success: function(data) {
console.log("Sucess");
}
});
console.log( "End" );
});
Because of same-origin security restrictions, you cannot issue ajax calls to domains other than the domain of your current web page.
Possible work-arounds depending upon what your actual problem is:
Build a server proxy on your domain that will fetch the web page from the other site for you so you can send the request to your own domain.
Use an iframe to display the content from another domain.
It is very common issue with Cross Domain Policy. If you are using jQuery Ajax then you can use JSONP to do cross domain query. Document at http://api.jquery.com/jQuery.ajax/

error: function(request, status) {
console.log(request, status);
},
success: function(data) {
console.log(data);
}
});
